What Is This Tool?
This converter transforms angular velocity values from degree per second (°/s), representing fast rotational speeds, into revolution per day (r/d), which expresses slower rotational rates over longer periods. It is especially useful for applications involving different timescale rotations.
How to Use This Tool?
-
Enter the angular velocity value in degree/second (°/s)
-
Select the target unit as revolution/day (r/d)

Common Use Cases
-
Converting gyroscope or IMU outputs showing fast rotations into longer-term rotational units
-
Describing planetary and lunar rotation rates in astronomy
-
Specifying slow spacecraft spin rates for mission analysis
-
Monitoring Earth rotation and angular drift in geodesy and timekeeping
Tips & Best Practices
-
Consider the difference in timescales when interpreting converted values
-
Use degree/second for rapid rotation measurements and revolution/day for slow rotations
-
Verify the practical relevance of conversion based on the application context
Limitations
-
Degree/second and revolution/day units operate on very different time scales
-
Conversion may not be meaningful if the difference between rapid and slow rotations is not accounted for
-
Not suitable for precision-dependent calculations requiring direct angular velocity comparisons
Frequently Asked Questions
-
What does degree per second measure?
-
Degree per second (°/s) measures the rate of angular change expressed in degrees within one second, indicating how fast something is rotating.
-
Why convert degree/second to revolution/day?
-
The conversion helps translate fast angular velocities into slower, long-term rotational rates commonly used in astronomy, geodesy, and spacecraft spin analysis.
-
Can these units be used interchangeably?
-
No, because degree/second is for fast rotations over short times, while revolution/day represents slow rotations over a full day; they suit different applications.
Key Terminology
-
Degree/second [°/s]

Revolution/day [r/d]
-
A measure of angular velocity indicating the number of complete 360° rotations occurring over 24 hours.
-
Angular velocity
-
The rate at which an object rotates or changes its angular position over time.
